The association agreement between MERCOSUR and the European Union (EU), signed on January 17, 2026, in Asunción and provisionally implemented since May 1, has begun to show its first concrete impacts on the regional bloc's agro-industrial trade. At the same time, the increase in exports has once again brought the operation of the quotas negotiated with the European market to the forefront of debate.
The EU granted MERCOSUR 21 tariff quotas for various agro-industrial products, opening new export opportunities with tariff benefits to one of the bloc's main trading destinations.
Among the most relevant quotas are those corresponding to fresh and frozen beef; poultry and pork —the latter still pending sanitary opening—; garlic, egg products, honey, rice, sugar, corn, sorghum, ethanol and dairy products.
Conversely, MERCOSUR granted the European Union 11 tariff-rate quotas. Four will be permanent—cheeses, garlic, infant formula, and powdered milk—while seven others, such as chocolates and packaged tomatoes, will evolve toward free trade after periods of between 10 and 14 years for tariff reductions following the implementation of the agreement.
Regional quotas and market access
One of the most striking aspects of the agreement is that several of the negotiated preferences are framed within quotas, and these quotas do not correspond to individual allocations per country, but rather to regional quotas administered for the entire MERCOSUR. This means that shipments made by any of the partners reduce the amount allocated to the bloc by the same regional quota.
In practice, the system operates under the criterion “First come, first served“(FCFS): the tariff benefit applies to shipments whose customs declaration is accepted first by the European authorities, until the available quota is filled. Meanwhile, and until MERCOSUR defines a regional distribution mechanism, the administration of these quotas continues under this chronological allocation scheme.”
In this context, Uruguay has already used 63% of the duty-free quota of rice enabled for this year, equivalent to part of the 6.667 tons available in the initial stage of implementation of the agreement, as confirmed on May 21 by the interim Minister of Foreign Affairs, Valeria Csukasi.
The official noted that MERCOSUR must inform the European Union in September how it will distribute quotas among its member states for each product. In Uruguay's case, the quotas of greatest interest are for beef and rice, as these products currently face high tariffs to enter the European market.
Meanwhile, the first Argentine operations also began using some of the regional quotas provided for in the agreement. On May 20, 2026, just 15 days after the provisional entry into force, Argentina filled its export quota. eggs to the European bloc.
Economy Minister Luis Caputo reported that sales reached 333 tons and corresponded to eggs from farms in Entre Ríos, Córdoba and Buenos Aires, processed before their distribution in Europe.
Something similar happened with the honeyAccording to the Minister of Deregulation and State Transformation, Federico Sturzenegger, on May 3, 2026, a company from Entre Ríos used up the tariff-free quota allocated to Mercosur for 2026 in just a few hours. The first shipment departed from Concordia, Entre Ríos, to Germany, with 20.986 kilograms acquired by the importer Langnese Honig GmbH & Co.
Furthermore, the official highlighted that, until the provisional entry into force of the agreement, Argentine honey was subject to a tariff of 17,3% to enter the European market.
A relevant aspect is that the technical team from the SENASA Entre Ríos Regional Center supervised the conditions of the extraction rooms, the homogenization plant and the sampling protocols, with the aim of strengthening the Argentine sanitary control system.
This verification is part of the requirements derived from the agreement itself, which in addition to the tariff reduction incorporates provisions related to the protection of geographical indications and compliance with sustainability standards, which helps products access international markets with greater added value.
How negotiated quotas work
Before this situation related to Argentina and Uruguay's compliance with quotasAndrea Russo, a graduate in International Trade, explained to Customs News that the discussion regarding quota administration is unrelated to the applicable rules of origin, which "remain in force as agreed, impacting both products that are inside and outside the quota."
In that sense, Andrea Russo pointed out that the big bet is to access the European market using the benefit of “zero tariff" inside of the intra-quota trade. Once the agreed annual tonnage is met, trade continues outside the quota, although without the full advantages of tariff reductions negotiated in the agreement, which are applied gradually and in annual percentages, according to each product.
As he explained, during trade negotiations, it is common practice for certain products considered "sensitive"—especially agricultural products—to establish this "careful" trade opening mechanism, as it is sometimes called, since it safeguards against potential shocks to trade flows in the event of a complete opening. This is achieved by regulating trade through the allocation of different quotas. In other words, a limited number of tons or units are established that can access the market with automatic tariff benefits.
Ms. Russo explained that, as stated in several articles by different authors and fellow negotiators, a specific regional mechanism for distributing and managing these quotas among MERCOSUR members has not yet been defined. Therefore, until such a mechanism is established, the EU applies the "first-come, first-served" criterion. In practice, this means that the European Union counts the quota as a single quota for MERCOSUR as a whole. Thus, the tariff benefit is allocated to the first shipments to enter the EU until the quota is filled.
Beyond the challenges related to managing quotas, the first operations have already begun to show the potential of the MERCOSUR-EU agreement to boost regional trade and expand access for agro-industrial products to high value-added markets.
Aduana News is the first Argentine customs newspaper to launch its digital version. With 20 years of experience, its publications and initiatives aim to provide the most relevant knowledge on customs issues in order to contribute to safe trade in the region.
